[0020] Due to the recent expansion of automobile use, many traffic accidents are occurring in various places. These traffic accidents cause serious socioeconomic damage and are a major public health problem worldwide.

[0021] Many countries are developing and implementing various methods to prevent traffic accidents in advance, and among them, traffic accidents that occur at crosswalks are particularly dangerous because they directly lead to loss of life.

[0022] A crosswalk signal is a device that signals pedestrians to cross the roadway. Crosswalk signal lights are usually installed on both sides of a crosswalk installed on the roadway, and red and green lights are used to transmit signals so that pedestrians can cross the roadway.

[0023] Recently, bollards have been installed at road crossings, children's safety zones, etc. to prevent vehicles from entering, thereby safely protecting pedestrians from vehicles.

[0024] These bollards are constructed by shaping various materials such as stone, concrete, metal or plastic into a rod shape and then burying them in the ground, or by fixing them to the ground using fastening means such as anchors.

[0025] Most of these conventional bollards are designed for aesthetic purposes, either to enhance their appearance or to serve only a very limited function of simply preventing vehicles from entering. As a result, their utility is very limited and they are uneconomical compared to their utility.

[0026] In order to solve these problems, the present invention aims to provide an auxiliary traffic light device and a control method using a bollard installed on a crosswalk and outputting a pedestrian signal in synchronization with a pedestrian detection result and a crosswalk pedestrian signal.

[0027] In order to achieve the above object, one embodiment of the present invention is an auxiliary traffic light device using a bollard, comprising: a bollard management unit that outputs preset operation control signals to a first bollard, a second bollard, and a third bollard; a first bollard installed in the center of a crosswalk and operated to display an image based on a pedestrian stop signal and a pedestrian walk signal on a floor surface in accordance with the operation control signal of the bollard management unit; a second bollard installed on one side of the first bollard in the direction in which a vehicle enters and operated to display an image based on a pedestrian stop signal, a vehicle stop signal, and a vehicle travel signal on a floor surface in accordance with the operation control signal of the bollard management unit; and a third bollard installed on the other side of the first bollard in the direction in which the vehicle exits and operated to display an image based on a pedestrian stop signal, a vehicle travel signal, and a pedestrian walk signal on a floor surface in accordance with the operation control signal of the bollard management unit.

[0029] In addition, the bollard device according to the above embodiment is characterized in that, when a pedestrian signal is detected from any one of the first to third bollards, the bollard device outputs a pedestrian stop signal, a pedestrian walk signal, a vehicle stop signal, or a vehicle driving signal by changing the signal to enable pedestrian crossing.

[0030] In addition, the second bollard according to the above embodiment is characterized by having a vehicle detection unit that detects the approach of a vehicle, and detects the movement of the approaching vehicle based on distance information and time information of the vehicle detected by the vehicle detection unit.

[0031] In addition, the bollard device according to the above embodiment is characterized in that it outputs an alarm signal to be exposed to pedestrians and vehicle drivers through the first to third bollards when movement of the vehicle is detected.

[0032] In addition, one embodiment of the present invention is a method for controlling an auxiliary traffic light device using a bollard, comprising: a) a step of causing a bollard device unit to output preset operation control signals to a first bollard, a second bollard, and a third bollard, and display a pedestrian stop signal, a pedestrian walk signal, a vehicle stop signal, and a vehicle driving signal on a floor surface, respectively, for the first bollard, the second bollard, and the third bollard; b) a step of confirming whether the bollard device unit is connected to a traffic signal control unit that outputs a traffic control signal through a network, and determining whether a traffic control signal is received from the traffic signal control unit; and c) a step of outputting an operation control signal, respectively, for the first bollard, the second bollard, and the third bollard in synchronization with the traffic control signal, upon receiving the traffic control signal.

[0033] In addition, the above embodiment is characterized by further including a step of: d) if the bollard device unit does not receive a traffic control signal due to the absence of a traffic signal control unit connected through a network in step b), changing and outputting a pedestrian stop signal, a pedestrian walk signal, a vehicle stop signal, or a vehicle driving signal in response to a pedestrian signal detected from any one of the first to third bollards to enable pedestrian crossing.

[0034] In addition, the bollard device according to the above embodiment is characterized in that it detects the movement of the vehicle based on the distance information and time information of the vehicle detected from the second bollard installed in the direction in which the vehicle enters, and outputs an alarm signal to the first to third bollards so as to be exposed to pedestrians and vehicle drivers when the movement of the vehicle is detected.

[0054] As shown in FIGS. 1 to 5, an auxiliary traffic light device using a bollard according to an embodiment of the present invention may be configured to include a bollard device unit (100) installed on a crosswalk and outputting a pedestrian signal in synchronization with a pedestrian detection result and a crosswalk pedestrian signal.

[0055] The bollard device (100) can be installed on a crosswalk where a traffic signal control unit (200) that outputs a traffic control signal is installed, and can be connected to the traffic signal control unit (200) through a network.

[0057] In addition, the bollard device (100) may output preset operation control signals for each of the first bollard (130), the second bollard (140), and the third bollard (150) when it is installed at a crosswalk without a traffic signal control unit (200) or a traffic signal control unit (200) connected via a network and cannot receive a traffic control signal.

[0058] In addition, when the bollard device (100) is installed at a crosswalk where a traffic control signal cannot be received, if a pedestrian signal is detected from any one of the first to third bollards (130, 140, 150), the bollard device can output a pedestrian stop signal, a pedestrian walk signal, a vehicle stop signal, and a vehicle drive signal to enable pedestrian crossing by changing the signal so that the pedestrian can cross the crosswalk.

[0059] To this end, the bollard device unit (100) may be configured to include a data communication unit (110), a bollard management unit (120), a first bollard (130), a second bollard (140), and a third bollard (150) connected through an IoT-based network.

[0060] The data communication unit (110) receives a traffic control signal output to a traffic light (300) from a traffic signal control unit (200) connected through a network, and outputs the received traffic control signal to the bollard management unit (120).

[0061] Here, the traffic control signal may include a traffic light (300) installed on a crosswalk, a pedestrian walk signal for pedestrians to cross the crosswalk, and a pedestrian stop signal for pedestrians to wait at the end of the crosswalk.

[0079] The data communication unit (141) performs data communication with the bollard management unit (120) to receive an operation control signal and outputs the received operation control signal to the second bollard control unit (142).

[0080] When the second bollard control unit (142) receives a received motion control signal, for example, a pedestrian walk signal, it outputs a control signal so that a still image of the second bollard vehicle is displayed on the floor in the direction of the crosswalk.

[0081] In addition, when the second bollard control unit (142) receives a pedestrian stop signal, it outputs a control signal so that a second bollard stop image is displayed on one horizontal surface and the floor surface of the second bollard (140).

[0082] In addition, when the second bollard control unit (142) receives a pedestrian stop signal, it outputs a control signal so that the second bollard vehicle driving image is displayed on the floor surface in the direction of the crosswalk.

[0083] In addition, the second bollard control unit (142) detects movement based on distance information to the vehicle (400) detected by the vehicle detection unit (144) and movement information per hour, and transmits the result of detecting movement according to whether the vehicle (400) is approaching to the bollard management unit (120).

[0084] In addition, when a pedestrian detection signal is input from the pedestrian detection unit (145), the second bollard control unit (142) transmits it to the bollard management unit (120) and outputs a control signal so that a second bollard still image, a second bollard vehicle driving image, or a second bollard vehicle still image corresponding to a pedestrian walk signal or a pedestrian stop signal received from the bollard management unit (120) is output.

[0085] Additionally, when the second bollard control unit (142) receives an alarm signal from the bollard management unit (120), it can control at least a portion of the light source unit (143) to blink.

[0086] The light source unit (143) is installed along the crosswalk direction of the second bollard (140) and along one or both sides of the longitudinal direction of the second bollard (140), and outputs a still image of the second bollard vehicle, a driving image of the second bollard vehicle, to the floor surface in the crosswalk direction, or outputs a still image of the second bollard to one horizontal surface of the second bollard (140) and the floor surface.

[0089] Additionally, the vehicle detection unit (144) provides distance and time information to the measured vehicle (400) to the second bollard control unit (142).

[0090] The pedestrian detection unit (145) detects a pedestrian located within a certain range, for example, 1 m, from the second bollard (140) and outputs a pedestrian detection signal to the second bollard control unit (142).

[0091] The third bollard (150) is installed on the other side of the first bollard (130) in the direction in which the vehicle (400) advances, and operates in accordance with the operation control signal of the bollard management unit (120) so that an image based on a stop signal for pedestrians, a driving signal for vehicles, and a walking signal for pedestrians is displayed on the floor surface. It may be configured as a rectangular member.

[0092] To this end, the third bollard (150) may be configured to include a data communication unit (151), a third bollard control unit (152), a light source unit (153), and a pedestrian detection unit (154).

[0093] The data communication unit (151) performs data communication with the bollard management unit (120) to receive an operation control signal and outputs the received operation control signal to the third bollard control unit (152).

[0103]

[0104] The following describes a control method of an auxiliary signal light device using a bollard according to one embodiment of the present invention.

[0105] FIG. 6 is a flowchart illustrating a control method of an auxiliary signal light device using a bollard according to an embodiment of the present invention, FIG. 7 is a flowchart illustrating a bollard control process in a state where a walk signal is input in the control method of an auxiliary signal light device using a bollard according to the embodiment of FIG. 6, and FIG. 8 is a flowchart illustrating a bollard control process in a state where a walk signal is not input in the control method of an auxiliary signal light device using a bollard according to the embodiment of FIG. 6.

[0106] As shown in FIGS. 1 to 8, a control method of an auxiliary signal light device using a bollard according to an embodiment of the present invention is such that a bollard device unit (100) outputs preset operation control signals to a first bollard (130), a second bollard (140), and a third bollard (150), and displays a pedestrian stop signal, a pedestrian walk signal, a vehicle stop signal, and a vehicle drive signal on the floor surface (S100) for each of the first bollard (130), the second bollard (140), and the third bollard (150).

[0107] The bollard device unit (100) checks whether it is connected to the traffic signal control unit (200) that outputs the traffic control signal through a network, and determines whether the traffic control signal is received from the traffic signal control unit (200) (S200).

[0108] As a result of the judgment at step S200, when a traffic control signal is received, the bollard device unit (100) outputs an operation control signal (S300) for each of the first bollard (130), the second bollard (140), and the third bollard (150) in synchronization with the traffic control signal of the traffic signal control unit (200), for example, a pedestrian crossing signal or a pedestrian stop signal and a vehicle right turn signal.

[0109] To explain step S300 in more detail, the bollard device unit (100) outputs a pedestrian signal and a vehicle signal (S310) to each of the first bollard (130), the second bollard (140), and the third bollard (150) according to the outputted motion control signal.

[0110] In step S310, if the motion control signal is a stop signal for the user to wait at the crosswalk, as shown in FIG. 9, the first bollard (130) outputs a first bollard still image (130a) on both sides of the first bollard (130) so that the pedestrian waits at the entrance to the crosswalk, the second bollard (140) outputs a second bollard still image (140a) for the pedestrian on one side, the second bollard vehicle driving image (140b) for the vehicle (400) is output toward the crosswalk, and the third bollard (150) outputs a third bollard still image (150a) and a third bollard vehicle driving image (150b) on one side.

[0111] In addition, in step S310, when the motion control signal is a crosswalk pedestrian signal, as shown in FIG. 9, the first bollard (130) may be changed to output a first bollard pedestrian image (130b) in the crosswalk direction, the second bollard (140) may be changed to output a second bollard vehicle still image (140c) in the crosswalk direction, and the third bollard (140) may be changed to output a third bollard pedestrian image (150c) in the crosswalk direction.

[0112] Continuing, the bollard device (100) controls the operation of the first bollard (130), the second bollard (140), and the third bollard (150) according to the pedestrian crossing signal, and detects the movement of a vehicle (400) approaching the crosswalk (S320).

[0113] As a result of the detection at step S320, when a vehicle (400) approaching the crosswalk is detected, the bollard device (100) outputs an alarm signal (S330) to warn of the approach of the vehicle (400) to the first bollard (130), the second bollard (140), and the third bollard (150), so that a pedestrian can confirm the approach of the vehicle (400).

[0114] At step S320, the bollard device (100) can detect the movement of the vehicle (400) based on the distance information and time information of the vehicle (400) detected from the second bollard (140) installed in the direction in which the vehicle (400) is entering.

[0115] In addition, the bollard device (1000) maintains the output of the alarm signal (S340) until a new traffic control signal is input to the first bollard (130), the second bollard (140) and the third bollard (150) or the movement of the vehicle (400) ends.

[0116] Meanwhile, as a result of the judgment at step S200, the bollard device (100) installed at a crosswalk where a traffic control signal is not received responds to a pedestrian signal detected from any one of the first bollard (130), the second bollard (140), and the third bollard (150) by changing the pedestrian stop signal, pedestrian walk signal, vehicle stop signal, and vehicle driving signal to enable pedestrian crossing and outputting them (S400).

[0117] To explain the S400 step in more detail, the bollard device unit (100) is configured to output operation control signals set for the first bollard (130), the second bollard (140), and the third bollard (150), as shown in FIG. 10, the first bollard (130) outputs a first bollard still image (130a) on both sides of the first bollard (130) so that a pedestrian waits at the entrance of the crosswalk, the second bollard (140) outputs a second bollard still image (140a) for a pedestrian on one side, and outputs a second bollard vehicle driving image (140b) for a vehicle (400) toward the crosswalk, and the third bollard (150) outputs a third bollard still image (150a) and a third bollard vehicle driving image (150b) on one side. Do it.

[0118] The bollard device (100) determines (S420) whether a pedestrian is detected from any one of the first bollard (130), the second bollard (140), and the third bollard (150) during the process of performing step S410.

[0119] As a result of the judgment at step S420, when a pedestrian is detected, the bollard device (100) outputs (S430) a second bollard vehicle still image (140b) in the direction of the crosswalk so that the vehicle (400) can stop at the second bollard (140) installed in the direction in which the vehicle (400) is approaching.

[0120] In addition, the bollard device unit (100) determines whether a movement of a vehicle (400) approaching from the second bollard (140) is detected (S440), and when the movement of the vehicle (400) approaching is detected, the bollard device unit (100) outputs an alarm signal to warn of the approach of the vehicle (400) to the first bollard (130), the second bollard (140), and the third bollard (150) (S450), so that a pedestrian can confirm the approach of the vehicle (400).

[0121] At step S440, the bollard device (100) can detect the movement of the vehicle (400) based on the distance information and time information of the vehicle (400) detected from the second bollard (140) installed in the direction in which the vehicle (400) is entering.

[0122] Continuing, the bollard device unit (100) outputs a changed motion control signal (S460) such that the first bollard (130) outputs a first bollard walking image (130b) in the direction of the crosswalk, the second bollard (140) outputs a second bollard vehicle still image (140c) in the direction of the crosswalk, and the third bollard (140) outputs a third bollard walking image (150c) in the direction of the crosswalk, as shown in FIG. 10.

[0123] Therefore, by being installed on a crosswalk and outputting a pedestrian signal in synchronization with the pedestrian detection result and the crosswalk pedestrian signal, it is possible to provide safe walking for pedestrians on the crosswalk.
